out4trout,
I know you mentioned the Watauga and Holston. *I haven't yet managed to get up and fish those tailwaters, but I can give some advice from my own experience. *If you're a wader, the Hiwassee tailwater is tough to beat. *You can wade at least in a few spots on pretty much any generation schedule other than spilling. *On one generator or none, you can wade an enormous amount of water. *I highly recommend it if you're ever down that way. *There's a website out there that gives a lot of good info on wading the Hiwassee (http://www.hiwassee.net). *Definitely be careful no matter which tailwater you fish,
